Abstract: Monolithic materials cannot fulfil the demands for the advanced industrial requirements. Therefore, composite materials which possess the combined properties of different constituents are developed. In this experimental work, Al 6061 was used as matrix and Al₂O₃, SiC and E glass short fibres were used as the reinforcement material. The composite specimen is fabricated through stir casting by varying the weight percentage of reinforcements and matrix materials. The investigation concluded that the load and sliding speed are expanded to improve the wear rate, and developing the sliding distance the wear rate is decreased. The different compositions of the materials are tested by using Pin on Disc apparatus to find the wear rate. From the experimental results the least wear rate is obtained in the composition (C₄) of 70% wt of Al 6061, 15% wt of Al₂O₃, 9% wt of SiC and 6% wt of E glass short fibre.

Keywords: wear rate; Al 6061; Al₂O₃; SiC; E glass fibre; stir casting.
